俱舍論疏 9.58

9.58

論「又別顯示至以當名顯」，此指名屬當也。此言輪王、獨覺、大覺入胎者取當名，入胎之時非輪王、獨覺、大覺等故。

On the Śāstra's 'Furthermore, it specifically demonstrates... designated by what they will become': this points out that the names pertain to what they will become. Here, saying that a wheel-turning monarch, solitary awakened one, or greatly awakened one enters the womb adopts the designation of what they will become, because at the time of entering the womb they are not yet a wheel-turning monarch, solitary awakened one, or greatly awakened one.
